Update GrammarCells constraint checks to fix empty completion menus #679

Closed HeikoBecker closed 10 months ago

HeikoBecker commented 10 months ago

The changes from #664 were causing some completion menus to become empty since the constraints were not set up to check for abstract dummy nodes. This PR addresses this issue by moving the earlier constraint test back to its original version. The filtering is then performed when building the concrete action list.

Can you add a test case for this?
